It's one thing to argue opinions, they're like assholes, everybody has one. But it's entirely another thing to argue facts. Don't go down that road without checking the facts first.
In this case, 3db is right. During WWII, the Russians became the masters of tank warfare. They defeated the Germans with superior tanks, artillery, other weapons, and tactics. In particular, the Russian T-34 tank was superior in quality and quantity. See this:

Yes, it's true we sent weapons and supplies to Russia. But those tanks and airplanes were small numbers compared to those that were built in Russia. The tanks we sent were light tanks, faster than our heavy tanks. But they were slower than the heavy Russian T-34. The airplanes we sent, mainly P-39s, were rejected for use by the US Army Air Force. It is said, the most useful thing we sent them were 2½ ton trucks. We sent lots of those, and the Russians didn't have anything like them.
